Calla lily plant named ‘Dozanalas’

ABSTRACT

‘Dozanalas’ is a new variety of calla lily plant having white colored spathes without a throat spot that produces 7-10 inflorescences per approximately 20 cm tuber. The flower stems are about 29-35 cm in height. The leaves are brownish green without maculations present and a smooth texture.

Botanical classification: Zantedeschia sprengeri.

Varietal denomination: ‘Dozanalas’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of callalily, botanically known as Zantedeschia sprengeri and hereinafterreferred to by the varietal name ‘Dozanalas’. ‘Dozanalas’ is a productof a planned breeding program, which had the objective of creatingZantedeschia hybrids for pot flower production in a wide range of colorswith a classic flower shape. The new cultivar is a seedling selectedfrom the crossing of Zantedeschia sprengeri variety ‘Helvetia’ (femaleparent, U.S. Plant Pat. No. 28,873) with Zantedeschia sprengeri variety‘Calgary’ (male parent, U.S. Plant Pat. No. 24,275). ‘Dozanalas’ wasselected in 2012 by the inventor in 't Zand, The Netherlands as oneflowering plant within the progeny of the stated cross.

The first act of asexual reproduction of ‘Dozanalas’ by tissue culturewas performed by the inventor in January of 2016 in 't Zand, TheNetherlands. Subsequent asexual reproductions by tissue culture at thesame location have demonstrated that the combination of characteristicsas herein disclosed for the new cultivar are retained and reproducedtrue to type through successive generations of asexual reproduction.

The following observations, measurements and comparisons describe plantsat approximately 8 weeks from planting directly in the soil in 't Zand,The Netherlands under greenhouse conditions, which approximate thosegenerally used in horticultural practice. Color references are made toThe 2001 R.H.S. Colour Chart of The Royal Horticultural Society ofLondon, 4^(th) Edition, except where general color terms of ordinarysignificance are used.

The present invention has not been evaluated under all possibleenvironmental conditions. The phenotype may vary with variations inenvironment without a change in the genotype of the plant.

The following traits have been repeatedly observed and determined to bebasic characteristics of ‘Dozanalas’ which, in combination, distinguishthis calla lily as a new and distinct cultivar:

-   -   1. Medium white colored spathes without a throat spot;    -   2. Brownish green colored leaves; and    -   3. No leaf maculations present.

The new variety is similar to its female parent in the following traits:white spathe color without a throat spot, spathe width and length, greenpeduncle color, and the absence of leaf maculations. However,‘Dozanalas’ exhibits a stronger flower curve than its female parent.Further, its female parent has a yellow/red spadix color and oval shapedleaves. The new variety is similar to its male parent in the followingtraits: white spathe color, spathe width and length, strong flowercurve, and green peduncle color. However, its male parent exhibits aspathe throat spot, a yellow/red spadix color, oval shaped leaves, andthe presence of leaf maculations.

When compared to calla lily plant named ‘Diva Siberia’ (U.S. Plant Pat.No. 32,492), both varieties exhibit white colored spathes without athroat spot and the absence of leaf maculations, but ‘Diva Siberia’ is avariety of Zantedeschia aethiopica, is much larger in stem height andspathe size than ‘Dozanalas’, and exhibits a sagittate leaf shape.
